Subject Ambari metrics collector -unble to restart
Date Sat, 07 May 2016 07:37:37 GMT
Ambari metrics collector was working fine for 6 months and suddenly it
stopped working. This is the error we are getting.

    hbase.rootdir - /mnt/data/ambari-metrics-collector/hbase
    hbase.cluster.distributed -false
    Metrics service operation mode -embedded
    hbase.zookeeper.property.clientPort - 61181
    quorum =localhost
